In general, the present inventions relates to systems and methods for use in pilot traffic alertness and awareness using sound signals in the pilot's headset for the pilot's head position to be guided to the target aircraft and target obstacle location. The pilot to locate the target aircraft using sound signals in the pilot's headset is instinctive and seamless, this is because the present invention provides sound signals that are of a natural neuro-stimuli for the pilot to comprehend in guiding the pilot to locate the target aircraft and target obstacle. This by the use of sound signals consisting of three dimensional audio effects and tonal sensations. In particular, the systems and methods of the pilot traffic alertness and awareness is a flight unit of controlling and sensory elements that generate appropriate sound signals; and thereby process the pilot's head position, receiving aircraft and stored navigational map target obstacle information; and additionally sending information to at least one mobile electronic device for the purpose of visually displaying guiding information directing the pilot's head position for the pilot to locate the target aircraft and target obstacle.

The present inventions, among other things, solves these needs by providing the systems and methods taught herein.

Thus, in general, and by way of example, there is provided in FIG. 1 a target aircraft 1012 flying within a time of collision 1000 depicted by a virtual 360 degree airspace zone. The calculation for time of collision by example may be linear, bilinear interpolation, nonlinear interpolation, simultaneous localization and mapping techniques. Wherein, the data is received from the target aircraft broadcast including Doppler, GPS, and navigation and depth sensory information, and additionally without limitation, of other means, such as rotation, gravitation, angular velocity, pitch, roll, magnetic, optical, electromagnetic signal strength, acceleration, and the like, known by those skilled in the art.

FIG. 1 further provides a perspective view showing the aircraft 1001 the aircrafts cockpit 1002, and with a portable flight unit 1004 that is placed in the on instrument panel 1003, and receives requested aircraft signal 1008 received by the said flight unit of a target aircraft 1012. This flight unit is at least calculating for the time of collision, and capturing and interpreting the head tracker 1007 of the pilot's head position 1010 from sensory information, whereby the said head tracker is affixed to the pilot's headset 1006. The said flight unit receives the pilot's head position from the head tracker, and determines the target aircraft location 1011, and thus where the pilot's head position must be directed to locate the target aircraft 1009. The flight unit then generates sound signals 1113 in the pilot's headset directing the pilot's head position for the pilot 1110 to locate target aircraft location. The said directing pilot's head position is further of a 360 degree motion for the pilot to locate the target aircraft.

Moreover, FIG. 2 presents further the head tracker 1007 communicating with the flight unit 1004 in the cockpit 1002 and a target aircraft 1012 has entered the time of collision 1000 from FIG. 1, wherein the said flight unit receives the data of the pilot's head position 1009 from the head tracker 1007 affixed to the pilot's headset 1007 and determines the location and time of collision of the target aircraft 1011. This information is communicated wireless to 2000 the mobile electronic device 2004 to indicate the direction of aircraft using a 3 dimensional arrow 2003 and displayed pop-up location of the aircraft 2002 on the mobile electronic device display, and wherein the mobile electronic device communicates 2001 with the flight unit. Further other electronic devices may be employed, by way of example, such a project, transparent electronic display, and the like known to those skilled in the art may be used.

A first aspect, by way of non-limiting example, relates to the type of sound signals 1113 consisting of three dimensional sound effects and tonal sensations generated by the flight unit 1004, and the sound signals are heard in the pilot's headset 1006 as illustrated exemplary in FIGS. 1-2 to locate at least one target aircraft 1000. The three dimensional sound effect may be the same and varying intensity and same and varying with reverberations in the pilot's headset. The three dimensional sound effect is calculated by the said flight unit using a means of calculating at least one head-related transfer function, using filters, and z-transform, Fourier transform of single and multidimensional, the frequency response of the system, and the like known by those skilled in the art. The three dimensional effecting sound signal in produced in accordance for the pilot to locate the target aircraft and target obstacle to each ear side. The three dimensional audio effect is interpreted to indicate to the sound location registered by the brain, wherein this may be of about eight side sounds in each ear with a such as front, right, front left, left; rear leaf, rear, and rear right directions, from about 16 side sounds in ear, from about 32 sounds in each ear, and, and about 32 sound or more in each ear. The three dimensional effect may vary by verbal sound with three dimensional effect, tonal sensation; and multiple verbal sounds and tonal sensations or a combination of these to indicate the target aircraft and target obstacle location in the pilot's headset.

As a further embodiment, the sound of pilots of two or more aircraft on a collision course, wherein each are notified by the said three dimensional effect sound signals in the pilot's headset; and where each pilot is to fly the aircraft to avoid collision in a predetermined time of collision and heading of the other aircraft. The flight unit can automatically communicate with another flight unit to coordinate the heading of each aircraft of the other pilot by means of receiving guiding sound signals in the headset to avoid the collision path of both aircraft. They, may also be notified by sound signals to locate the other pilot's head direction and notification of directions to avoid one or multiple aircraft and obstacle direction using multiple three dimensional effects, tonal sensations, or a combination of these. In addition, if the flight unit is part of a drone, the drone is flown automatically by the flight unit once a predetermined flight collision is known, and the piloted aircraft receives guiding sound signals as to where to fly. This is not within limitation of flight, but aircraft taxiing, takeoff, and landing.

And, by way of example, the mobile electronic device graphically displays information from at least one three dimensional arrow signal directing the pilot's head position to the location of one and multiple target aircraft and target location. This may further be combined with sound signals into the pilot's headset to locate the one and multiple target aircraft and target location. The graphically displayed information from the flight unit further may include relevant flight information, target aircraft information, weather, navigational maps, and controlling the configurations of one or multiple time of collision that is graphically displayed by the mobile electronic device. This may be further capable by means of verbal commands to change the configurations of the flight unit stored by the mobile electronic device.

The pilot is capable of receiving the sound signal consisting of three dimensional sounds and tones to indicate a first target aircraft and target obstacle, and a second sound signal to indicate a second, and so forth to indicate target aircraft and target obstacle. The configuration of the systems and methods further may have a single and multiple beeps to indicate a second aircraft, third aircraft, and so forth of target aircrafts and target obstacles within the time of collision. As an embodiment of the systems and methods, the pilot may configure verbal commands, whereby the flight unit contains voice recognition capability to define the sound signal and beep for target aircraft and target obstacle. As a second embodiment, the pilot can predetermine multiple sound signals and beeps for one and multiple time of collisions of target aircrafts and target obstacles. The methods and systems may have a set predetermined non-adjustable time of collision for safety of about 5 seconds, of about 10 seconds, of about 30 seconds, of about 1 minute, of about 3 minutes, and more than 3 minutes.

And, yet further the sound signal may further be discontinuous to allow the pilot to recognize more than one signal being sent in the pilot's headset indicating more than one target aircraft and target obstacle. The discontinuity of sound signal may be of about 1 second, of about 3 second, of about 5 second, of about 20 seconds, and more than 20 seconds. The discontinuity of the sound signal may have verbal information from the methods and systems, and of the following: verbal description of the sound signal, identification of target aircraft and target obstacle, meaning of the sound signal, such as target aircraft identified, and time of collision, and the like sent the pilot's headset during the discontinuity between sound signal, which does not produce a three dimensional sound.

In addition the sound signal providing target location guidance for the pilot in the pilots headset are tonal sensations. The tone properties may be a variation in intensity of modulation, such as a tremolo effect, variation in phase, or a combination of these. The tremolo effect, for example, is stronger when the pilot's head position is turned to the location of the target aircraft and target obstacle, and weaker when turned away as the signal will grow weaker.

And, further in addition, in accordance with one or more aspects of the systems and methods, the sound signals indicate flight assisted behavior. The said sound signals consisting of three dimensional audio effects, tone, and mixed verbal commands, or a combination thereof offering flight notification instructions. This for example, landing and aligning with the airstrip as the aircraft is needed to be tilt based on navigational stored maps and possibly camera and LIDAR information, wherein the sound signal intensity is three dimensional to indicate the airplane movement without having to visualize instrument data with verbal commands, such as move the aircraft left, and as the pilot moves the aircraft left, the sound signal grows weaker when reaching the right alignment position. The flight assisted information is without limitation to additionally being graphically displayed by a mobile electronic device transparent display, and projector with the said sound signals.
